48V DC Redundancy Module (Cat. No. 1606-XLERED)
This dual redundancy module can be used to build 1+1 or N+1
redundant systems.
The device is equipped with two input channels, each 10 A
nominal, which are individually decoupled by using diode
technology. The output can be loaded with nominal 20 A.
The device does not require an additional auxiliary voltage and
is self-powered, even in case of a short circuit across the output.
The device has a monitoring circuit included and is the perfect
choice when the power supply has no DC-OK function. Two
light-emitting diode (LEDs) and two relay contacts signal when
one of the two input voltages is not in range due to a non-
functioning or disconnected power supply.
The unit is slender and only requires 32 mm (1.26 in.) width on the
DIN rail.
Buffer Module (Cat. No. 1606-XLSBUFFER)
This buffer module is a supplementary device for 48V
DC/DC converters. It delivers power to bridge typical
supply voltage faults or extends the hold-up time after
turn-off of the input power.
In times when the DC/DC converter provides
sufficient voltages, the buffer module stores energy in
integrated electrolytic capacitors. If there is a supply
voltage fault, then this energy is released again in a
regulated process.
